RECOlL-GUN WITH SPECIAL DEVICES FOR PROTECTING THE SLIDE-TRACKS FROM DUST..

SPECIFICATION forming part of Letters Patent No. 756,120, dated March 29, 1904.

Application filed July 28, 1902.

To all whom it may concern.-

Be it known that I, Orro LAUBER, a subject of the Emperor of Germany, and a resident of 36/2 Holsterhausen, Essen on the Ruhr, Germany, have invented certain new and useful Improvements in Recoil-Guns with Special Devices for Protecting the Slide-Tracks from Dust, of which the following is a specification.

This invention relates to guns with barrelrecoil, and has for its object to provide means for protecting the slide-track from dust.

In guns with barrel recoil as heretofore constructed with slide tracks, there are parts of the track which are not covered by the guide-claws of the barrel, and therefore not protected from dust and dirt. It follows in consequence that in moving the gun from place to place dust or dirt settles upon and adheres to the oily surface of the slide-track and seriously interferes with the recoil and running-out movements of the gun-barrel in firing. This interference is precluded by the present invention through the use of felt plates v or the like, which are so mounted upon the gun-barrel or upon the cradle that they will protect the slide-trade from dust and the like.

In the drawings two embodiments of the invention are illustrated by the way of example, Figure 1 showing an embodimentin-which the felt plates are mounted upon the gun-barrel, the parts of the gun which come under consideration being shown in side elevation. Fig. 2 is a section on the line 2 2, Fig. 1, on an enlarged scale. Fig. 3 is a section on the line3 3, Fig. 2, looking from the left. Fig. 4 is a section onthe line 4 4, Fig. 3; and Fig. 5 is a view corresponding to Fig. 2, in which is shown a second embodiment of the inventi0nthat is to say, with the felt plates mounted upon the cradle.

The gun-barrel-A is guided upon the cradle B in a well-known manner. For this purpose the guide-claws C are arranged on either side of the gun-barrel and engage the slide-track through the medium of linings D, of brass. The linings D are provided outside of the guide-claws with heads E, which, on the one hand, prevent the sliding of the linings longi- Serial No. 117,347. (No model.)

tudinally in the claws and, on the other hand,- serve for securing the sheaths F, which inclose the free-lying portions of the slide-track with one longitudinal edge abutting in dusttight relation against the gun-barrel. These sheaths F constitute the supports for the felt plates G in the embodiment shown in Figs. 1 to 4, which felt plates are secured through the medium of the rivets H to the inner faces of those portions of the sheaths F which are opposite the under side of the slid e-track b. Obviously these felt plates could without departing from the essence of this invention be arranged on the inner face of another portion of the sheath turned toward the slidetrack, or they could completely envelop the slide-track after the manner of the brass linings. In firing, the gun-barrel, together with its guide-claws, recoils, whereupon the felt plates slide along the track.

The embodiment shown in Fig. 5 diflersslide-track, are secured to the side walls of the cradle B. They consequently remain at rest during the recoil and running-out movement of the gun-barrel, while the under faces of the claws and sheath slide along the felt plates.

Having thus described the invention, the following is what is claimed as new therein:

1. In a gun with barrel recoil, the combination of the slide-track, the gun-barrel mounted on the track through the medium of guideclaws, sheaths covering portions of the track not covered by the claws, and packings or plates of felt or the like introduced between the sheaths and the track.

2.. In a gun with barrel recoil, the combination of the slide-track, the gun-barrel mounted on the track through the medium of guideclaws, sheaths covering portions of the track not covered by the claws, and packings or plates of felt or the like introduced between the sheaths and the track, secured to and moving with the sheaths.

3. In a gun with barrel recoil, th-- combination of the slide-track, the gun-barrel mounted on the track through the medium of guideclaws, sheaths enveloping portions of the track not covered by the claws, and packings or plates of felt or the like introduced between the sheaths and the track, secured to the sheaths between the inner faces of their under sides, and the under sides of the track, so that they partake of movements of the gunbarrel.

4. The combination with the cradle formed with a slide-track, a barrel, and guide-claws secured to the barrel, and embracing the slidetrack, of linings for the guide-claws having heads extending outside thereof, and sheaths secured to said linings. 1

5. In a field-gun with recoiling barrel, the combination of a tubular cradle, having a closed cross section,- ribs arranged on the outer surface of the cradle, slides attached to the gun, and engaging the said ribs, and protecting-strips arranged between the slides and covering the ribs.

6. In a gun with barrel recoil, a cradle consisting of a circumferentially-closed hollow body containing the recoil-check and recuperating means, a track on said cradle adapted to guide the gun-barrel in its recoil and running-out movement and mounted on the outside of said hollow body, a gun-barrel provided with means engaging said track, and plates of felt or the like attached to the gunbarrel, for the purpose of protecting the track from dust.

The foregoing specification signed at Dusseldorf,Germany, this 9th day of July, 1902.
